& the link because... well, jpgs are useless...
the thumbnail doesn't match the rack though!!!
pip slope & adsr: depends if you use both of them or not - I'd try taking the adsr out & see if it makes a difference to your patching... why the adsr & not the pip slope - it's quite big and will free up more space... if you decide you do need an adsr - there are smaller ones...
filters: get the one(s) you like the sound of best...
layout: I'd probably move maths (& the adsr if you decide to keep it) down and the filter & veils up - order depends on if you usually go vco->filter->vca or vco->vca->filter... I'd probably try to move the midi module up (to the left of pams)
suggestions: more modulation (batumi or another similar sized quad lfo), attenuators, switches, a matrix mixer, a multi-fx module (I like fx aid pro)... but by the time you add those you'll need a bigger rack (get a mantis!)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
